$\displaystyle \tt \bigg(3\frac{4}{9}-1\frac{11}{12}\bigg)\cdot3\frac{9}{11}+6:\frac{12}{25}-2\frac{1}{3}=16\\\\\\1). \ 3\frac{4}{9}-1\frac{11}{12}=3\frac{16}{36}-1\frac{33}{36}=2\frac{52}{36}-1\frac{33}{36}=1\frac{19}{36};\\\\2). \ 1\frac{19}{36}\cdot3\frac{9}{11}=\frac{55}{36}\cdot\frac{42}{11}=\frac{105}{18}=5\frac{5}{6};\\\\3). \ 6:\frac{12}{25}=6\cdot\frac{25}{12}=\frac{25}{2}=12,5;\\\\4). \ 5\frac{5}{6}-2\frac{1}{3}=3\frac{3}{6}=3,5;\\\\5). \ 12,5+3,5=16;$
